General Information

PRODUCT INFORMATION

CINCH ATZ is a selective herbicide that may be used before planting, before or after emergence (see directions) for control of most annual grasses and broadleaf weeds in corn.

CINCH ATZ can also be used before crop emergence for control of most annual grasses and broadleaf weeds in grain or forage sorghum, provided the sorghum seed has been properly treated by the seed company with “Concep” or “Screen”. This product may be tank mixed with other herbicides specified on the label for weed control in conventional, minimum-till, and no-till corn, grain sorghum, or forage sorghum.

Note: Tank mixtures are permitted only in those states where the tank mix partner is registered. Refer to and follow the label of each tank mix product used for precautionary statements, directions for use, geographic and other restrictions.

When tank-mixing or sequentially applying, atrazine or products containing atrazine to corn or sorghum, the total pounds of atrazine applied (lbs ai/A) must not exceed 2.5 lbs a.i. per year.

Maximum Broadcast Rates for Atrazine

- If no atrazine was applied prior to corn emergence, apply a maximum of 2 lb ai/A broadcast. If a postemergence treatment is required following an earlier herbicide application, the total atrazine applied may not exceed 2.5 lb ai/A per calendar year.

- 2.0 lb ai/A as a single preemergence application on soils that are not highly erodible or on highly erodible if at least 30% of the soil is covered with plant residues, or

- 1.6 lb ai/A as a single preemergence application on highly erodible soils if < 30% of the surface is covered with plant residues, or 2.0 lb ai/A if only applied postemergence.

- If no atrazine was applied prior to corn emergence, apply a maximum of 2 lb ai/A broadcast.

Following many years of continuous use of atrazine (one of the ingredients in CINCH ATZ), and products chemically related to atrazine, biotypes of some of the weeds listed on the label which are controlled by the atrazine component have been reported to develop resistance to this and chemically related herbicides. Where this is known or suspected, and weeds controlled by this product are expected to be present along with resistant biotypes, we recommend the use of CINCH ATZ in combination or in sequence with registered herbicides which do not contain triazines. Consult with your State Agricultural Extension Service for specific recommendations.

Precautions: (1) If sorghum seed is not properly pretreated with “Concep” or “Screen”, DuPont CINCH ATZ will severely injure the crop. (2) Injury may occur to sorghum following the use of CINCH ATZ under abnormally high soil moisture conditions during early development of the crop.

CINCH ATZ alone or in tank mixture with “AAtrex”, “Balance”, CINCH, or “Princep” may be applied early preplant, preplant surface, preplant incorporated, or preemergence on corn, in water or fluid fertilizer. Apply postemergence treatments of CINCH ATZ to corn, alone or in combination, using water only as the carrier. CINCH ATZ may be applied in tank mix combination with “Gramoxone” Inteon , “Landmaster” BW, “Touchdown” or “Roundup UltraMax” (or other formulations of glyphosate) with or without the above herbicides preplant surface or preemergence to corn. CINCH ATZ alone may also be applied on sorghum early preplant, preplant incorporated, preplant surface, or preemergence in water or in fluid fertilizer.

CINCH ATZ may be applied in water by aircraft. Applications in fluid fertilizer should be only by ground equipment.

To avoid spray drift, do not apply under windy conditions.

Avoid spray overlap, as crop injury may result.

Do not apply this product through any type of irrigation system.

Do not apply under conditions which favor runoff or wind erosion of soil containing this product to nontarget areas.

To prevent off-site movement due to runoff or wind erosion:

1. Avoid treating powdery dry or light sand soils when conditions are favorable for wind erosion. Under these conditions, the soil surface should first be settled by rainfall or irrigation.

2. Do not apply to impervious substrates, such as paved or highly compacted surfaces.

3. Do not use tailwater from the first flood or furrow irrigation of treated fields to treat nontarget crops, unless at least ½ inch of rainfall has occurred between application and the first irrigation.

Where reference is made to weeds partially controlled, partial control can either mean erratic control from good to poor or consistent control at a level below that generally considered acceptable for commercial weed control.

Dry weather following preemergence application of CINCH ATZ or a tank mixture may reduce effectiveness. Cultivate if weeds develop in conventional tillage corn or sorghum.

Observe all precautions and limitations on the label of each product used in tank mixtures.

Thoroughly clean sprayer or other application device before using. Dispose of cleaning solution in a responsible manner.

Do not use a sprayer or applicator contaminated with other materials, or crop damage or sprayer clogging of the application device may occur.

Do not apply metolachlor containing products such as “Inter 8E II” herbicide or “Inter Plus II” herbicide in mixture or as sequential applications with CINCH ATZ.

CINCH ATZ Rate Limitations – Corn and Sorghum

Sorghum: Where there are state/local requirements regarding atrazine use (including lower maximum rates and/or greater setbacks) which are different from the label, the more restrictive/protective requirements must be followed. Certain states may have established rate limitations within specific geographical areas. Consult your state lead pesticide control agency for additional information. It is a violation of the label to deviate from state use regulations.

Note: For purposes of calculating total atrazine active ingredient applied, CINCH ATZ contains 3.1 lbs. a.i. atrazine + relateds per gal. (0.775 lb. a.i./qt.).

FOR ALL SOIL APPLICATIONS PRIOR TO CROP EMERGENCE

- On Highly Erodible Land (as defined by the Natural Resource Conservation Service)

If conservation tillage is practiced, leaving at least 30% of the soil covered with plant residues at planting, apply a maximum of 5.2 pt./A as a broadcast spray.

If the soil coverage with plant residue is less than 30% at planting, a maximum of 4.2 pt./A may be applied.

- On Land Not Highly Erodible

Apply a maximum of 5.2 pt./A as a broadcast spray.

FOR POSTEMERGENCE APPLICATION TO CORN

If no atrazine was applied prior to corn emergence, apply a maximum of 5.2 pt./A broadcast. If a postemergence treatment is required following an earlier herbicide application, the total atrazine applied may not exceed 2.5 lbs. active ingredient (6.4 pt. of CINCH ATZ) per acre per calendar year.

APPLICATION PROCEDURES

Early Preplant (Corn): Use on medium- and fine- textured soils with minimum-tillage or no-tillage systems in CO, IA, IL, IN, KS, KY, MN, MO, MT, ND, NE, SD, TN, WI, and WY. Apply 2/3 the specified rate of CINCH ATZ as a split treatment 30-45 days before planting and the remainder at planting.. Applications made less than 30 days prior to planting may be as either a split or single treatment. Use the lower rate for light expected weed infestations and the higher rate for heavy expected weed infestations.

On medium- and fine-textured soils with minimum- or notillage systems in DE, MD, MI, NY, OH, PA, VA, and WV, early preplant applications may be applied following the directions for use above. If the amount of rainfall results in unsatisfactory length of weed control following the earlier treatment, a postemergence application of an appropriately labeled broadleaf and/or grass weed herbicide may be used, i.e., atrazine, DuPont BASIS, BASIS GOLD, ACCENT, ACCENT GOLD, STEADFAST or dicamba.

If the postemergence treatment includes the herbicide used early preplant, do not exceed the labeled rate for corn on a given soil texture. Observe all directions for use, precautions, and limitations on the label of the postemergent herbicide.

DuPont CINCH ATZ may be used according to the above directions to control winter wheat planted as a cover crop in IN, KY, and OH, in addition to providing residual weed control. The wheat must be less than 6 inches tall (preferably still in a dormant or semi-dormant state coming out of winter) at the time of application. Depending on rainfall, 10-20 days may be required to completely kill the wheat. In the event that adequate rainfall does not occur, control of the winter wheat may be unsatisfactory and the application of a contact herbicide (i.e., “Gramoxone” Inteon , “Touchdown” or “Roundup UltraMax”) may be required before planting the crop.

CINCH ATZ may be applied in the fall, as a single application, for control of the winter weeds listed on the label within the ecofallow (no-till) production areas of NE and KS where wheat (or other small grain cereals) will be rotated to corn. The application must be made to untilled wheat stubble in the fall following wheat harvest, but before soil freeze-up. The ground must remain untilled through the establishment of the corn crop.

On medium- and fine-textured soils following final seedbed preparation in the Blacklands and Gulf Coast areas of TX, an early preplant application of CINCH ATZ at 3.2-3.8 pt./A may be made 30-45 days before planting. Grass suppression of 2-3 weeks after planting can be expected as a result of this application. Do not incorporate or disturb the soil before planting, and avoid moving the soil during the planting operation. A follow-up application of CINCH may be needed in fields with a history of heavy grass pressure. Apply after planting, but before corn and grass weeds emerge.

Notes: (1) If a follow-up application of CINCH is needed, do not exceed a total of 1.6 lbs. a.i. of S-metolachlor per acre, including the preplant CINCH ATZ application on medium or fine-textured soils. On fine-textured soils with more than 3% organic matter, do not exceed 1.9 lbs. a.i. of S-metolachlor.

[To determine the total lbs. a.i. of S-metolachlor per acre, use the following 2-step method:

A. Determine the lbs. a.i. of S-metolachlor applied as CINCH ATZ (2.0 pt. = 0.6 lb. a.i. of S-metolachlor); then,

B. If CINCH is to be used, add the lbs. a.i. to be applied in these products to the lbs. in Step A above.]

(2) To the extent possible, do not move treated soil out of the row or move untreated soil to the surface during planting, or weed control will be diminished.

NOTES:

Cocklebur; giant ragweed; signalgrass (Brachiaria); velvetleaf; yellow nutsedge: Control of these weeds can be erratic, especially under dry weather conditions. Control escaped weeds with cultivation or application of an appropriate EPA-registered postemergence herbicide. On fine-textured soils, only partial control can be expected.

Do not exceed the rate on highly erodible land with less than 30% plant residue cover. Control of certain weeds may be reduced and a tank mix partner or an application of a postemergence herbicide may be needed.

Split applications can be made less than 30 days before planting if desired.

Restricted Entry Interval

24 hours

Exception: If the product is soil-injected or soil-incorporated, the Worker Protection Standard, under certain circumstances, allows workers to enter the treated area if there will be no contact with anything that has been treated.
